The invention relates to a motor blower for producing an air blast toatomize oil in a burner and to mix the air and oil for combustion.

The object of the improvement is to provide a blower communicating withan oil burner for furnishing a blast of air to the burner for atomizingoil, which may be supplied thereto in any usual manner, the mix ture ofthe atomized oil and air being in suitable proportions to supportcombustion, a heating jacket preferably surrounding the air pipe, and aheating drum being also provided to preheat the blast before it reachesthe burner.

The blower may be operated by any suitable power means, but for thepurpose of illustration the above and. other objects may be attained byassociating the blower with an oil heated steam engine boiler, theblower being driven by a steam turbine operated by live steam from theboiler the air blast passing from the blower through an air heating drumsurrounding the stack of the boiler and then to the burner, a heatingjacket also surrounding a portion of the air pipe, the eX- haust steamfrom the engine passing through said jacket to the blast nozzle in thestack of the boiler.

An embodiment of the invention is illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of an oil heated boilerand steam engine showing the im proved blower mechanism associatedtherewith, and

Fig. 2, a top plan view of the same.

Similar numerals of reference indicate corresponding parts throughoutthe drawing.

A vertical steam boiler of usual construction is shown at 1, arranged tobe heated by the oil burner 2 which is supplied with fuel oil, from anysuitable source of supply, through the pipe 3. The upper end of theboiler is preferably conical as indicated at 4 Serial No. 59,8551.

terminating in the stack 5, the exhaust nozzle 6 exhausting into thestack for the induction of draft. A hot air drum 7 surrounds the stackand the conical upper end of the boiler.

Live steam from the boiler is carried 5 through the pipe 8 to the steamchest 9 of a steam engine 10, which may be of any usual construction.Exhaust steam from the en gine 10 is received in the pipe 11 whichcommunicates with one end of a jacket 12 the other end of said jacketbeing connected to a pipe 13 which communicates with the exhaust nozzle6.

A rotary blower 14, of any usual and well known construction, exhaustsinto a pipe 15 which leads through the jacket 12 and communicates withthe heating drum 7, this pipe being preferably tangential to the heatingdrum and communicating with the lower portion thereof. 6

An outlet pipe 16, which is also preferably tangential to the heatingdrum, communicates with the upper reduced end portion of the same andleads to the burner 2 whereby a continuous blast of heated air is forced6- through the burner, atomizing the oil and mixing with the same forcombustion.

The blower 14 may be operated by any available power, and in thedrawings a steam turbine 17 is illustrated as directly connected 5 tothe blower, and driven by live steam from the boiler, which is conveyedto the turbine through a pipe 18, which may communicate with the steampipe 8. The steam fromthe turbine exhausts through the pipe 19, which 86may, if desired, be connected to the stack of the boiler to induce drafttherein.

From the above description and an inspection of the accompanyingdrawings it is evident that a blast of air is provided for the oil 8burner, the air being preheated by recuperation from the exhaust steamfrom the engine and radiation from the boiler while the blower may beoperated by live steam from the boiler, the combination forming a self-9 operated or self-energized unit.

I claim:

The combination with a steam engine, a steam boiler therefor and an oilburner for the boiler, of a blower, a conical air heating drum at thetop of the boiler, a pipe connecting the blower to the lower portion ofthe drum, a jacket surrounding said pipe, means for passing exhauststeam from the engine through said jacket, and a pipe connecting theupper portion of the drum to the burner.

In testimony that I claim the above, I have hereunto subscribed my name.
